Would it be ok to use a Adcom GTP-600 integrated amp for these headphones?
Or a Cambridge Audio Azur 640A V2.0 ......
Will i be losing much performance by doing this instead of a dac/headphone amp?

If i will what would you suggest?
EDIT::::::::
Right now i'm looking into maybe running a Matrix M-stage amp or a Little Dot MK V but i still don't know what dac to consider.
Do you guys think these amps would do well with the 780's?
Any suggestions on a dac to pair with it?

Welcome to Head-Fi.

Those headphones are not notoriously difficult to drive, and the integrated manufacturers you name are likely to have decent headphone outputs in their units. My Onkyo integrated works quite well with the HFI-780, as does my Adcom preamp (not listed in my profile because I use my Adcom separates as a back-up). Your DAC is a separate question though.

I have a few amplifiers and in comparison with my moderately priced Zero they don't sound half as good, perhaps some integrated amps are better than others but more often than not they aren't built for that and it ends up being somewhat of an afterthought.

I would also suggest solid-state over a tube amp for the Ultrasones.
